Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
The crops may be referred to as oilseed sunflower crops. These seeds are usually pressed to extract their oil. Striped sunflower seeds are primarily eaten as a snack food; as a result, they may be called confectionery sunflower seeds. The term "sunflower seed" is a misnomer when applied to the seed in its pericarp (hull).
Seedlings of 3 species, including interior spruce were planted with frozen root plugs (frozen seedlings) and with thawed root plugs (thawed seedlings). Thawed root plugs warmed to soil temperature in about 20 minutes; frozen root plugs took about 2 hours, ice in the plug having to melt before the temperature could rise above zero.
The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule ...
Sunflower seeds are generally planted only an inch deep in the ground. When such shallow planting is done in moist and soaked earth or soil, it increases the chances of diseases such as downy mildew. Another major threat to sunflower crops are broomrapes, a family of plants which parasitize the roots of various other plants, including ...
Seeds about 60% dry matter 87: Physiological ripeness: back of the anthocarp yellow. Bracts marbled brown. Seeds about 75–80% dry matter 89: Fully ripe: seeds on inner third of anthocarp dark and hard. Back of anthocarp brown. Bracts brown. Seeds about 85% dry matter Principal growth stage 9: 92: Over ripe, seeds over 90% dry matter 97: Plant ...
Seeds can be difficult to acquire, and some plants do not produce seed at all. Some plants (like certain [4] plants modified using genetic use restriction technology) may produce seed, but not a fertile seed. [5] In certain cases, this is done to prevent the accidental spreading of these plants, for example by birds and other animals. [6]
Globally, sunflowers are the fourth most important oil crop. Most of the sunflower seed crop is crushed for oil, and most of the oil is consumed by humans. A major byproduct of crushing is protein-rich cake, an excellent feed for livestock. A tiny proportion of the global sunflower crop is directly eaten as “nuts” or kernels.
